Monthly income and savings ratio is 11 : 2
The savings is ₹ 2500.
Let the monthly income be ₹ ‘x’
According to the question,
₹ x\ ∶\ ₹ 2500 = 11\ ∶\ 2
\rightarrow\ \frac{x}{2500}\ =\ \frac{11}{2}
\rightarrow\ 2x\ =\ 11\times2500
\rightarrow\ x\ =\ \frac{11\times2500}{2}
\rightarrow\ x\ =\ 13750
\therefore The monthly income of the family is ₹ 13750
We know,
Expenditure = (Monthly income – Monthly savings)
\therefore Expenditure is = (₹ 13750 - ₹ 2500)
